LED Display Drivers
The EEPROM register provides access control of the
EEPROM blocks. EEPROM blocks can be locked to pre-
vent alteration of data within the block. Locking a block

EEPROM Copy Flag
Set to 1 when: Copy Data command executed.
Cleared to 0 when: Copy Data command completes.
Note: While EEC = 1, writes to EEPROM addresses are ignored.
Power-up default: 0
EEPROM Lock Enable
Host write to 1: Enables the Lock command. Host must issue Lock command as
next command after writing lock enable bit to 1.
Cleared to 0 when: Lock command completes or when Lock command is not the
command issued immediately following the Write command used to set the lock
enable bit.
Power-up default: 0
Undefined
EEPROM Block 1 Lock Flag (Parameter EEPROM 60h–7Fh)
0: EEPROM is not locked.
1: EEPROM block is locked.
Factory default: 0
EEPROM Block 0 Lock Flag (User EEPROM 20h–2Fh)
0: EEPROM is not locked.
1: EEPROM block is locked.
Factory default: 0
disables write access to the block. Once a block is
locked, it cannot be unlocked. Read access to EEPROM
blocks is unaffected by the lock/unlock status.
